I would like to use mutate (gsub) on "text" fieldname to replace unicode value of emoticons to respective string values. An example -

`"\ud83d\ude27" replaced by "emoticon_anguished"`

I tried to escape single backslash by two, as following. Replacement is not working.

```
filter {
        mutate {
                gsub => [
                                "text", "\\ud83d\\udc7f", " emoticon_imp ",
                                "text", "\\ud83d\\ude3e", " emoticon_pouting_cat "
                ]
        }
}

```

Any help? thank you.

I think, I am able to solve it. Instead of using emoji's unicode, we need to simply use emoji itself. like the following.

```
    mutate {
            gsub => [
                                    "text", "👿", " emoticon_imp ",
                                    "text", "😾", " emoticon_pouting_cat "
                           ]
                  }
```
